The cast-in-place wall construction process needs to use a casting template, the existing cast-in-place template is a whole smooth plate, and a plurality of casting templates are built together to form a casting mold cavity. For a cast-in-place wall body built by taking a formed supporting beam as a supporting structure, a pouring template is required to be built below the supporting beam to form a pouring cavity together with the supporting beam, and because a large amount of foam exists in slurry, the volume of the slurry is reduced after the slurry is solidified, and a part of empty area is generated above the pouring cavity, therefore, in the existing cast-in-place process, a secondary pouring mode is generally adopted to reduce the volume of the empty area so as to enable the empty area to meet the construction requirements. In addition, according to the construction requirements, when the wall is not completely solidified after being cast and formed, the top end of the wall needs to be trimmed to be trapezoidal or triangular, and the cast-in-place construction process has more working procedures and is not beneficial to improvement of construction progress and construction quality.

Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
The embodiment discloses a cast-in-place wall top closing-up processing method, as shown in fig. 2 to 5, a casting template 1 adopted in the closing-up processing method comprises a main body part 10 and a movable part 11 connected with the main body part 10, wherein the movable part 11 is pivoted with the main body part 10, so that the movable part 11 can swing left and right relative to the main body part 10, an extensible member 12 is arranged on the movable part 11, and the extensible member 12 is used for adjusting the length of the movable part 11; referring to fig. 1, the closing process includes:
s1: building a pouring mold cavity 13 by using the pouring template 1, and adjusting the pivoting angle of the movable part 11 to enable the movable part 11 to deviate outwards or inwards from the main body part 10 by an angle alpha (shown in fig. 2 and 5), so that the volume of the pouring mold cavity 13 is effectively expanded, the top end of the movable part 11 is abutted against the built supporting beam 2, and at the moment, the pouring mold cavity 13 is formed by the pouring template 1, the supporting beam 2 and the bottom ground together;
s2: pouring slurry into the pouring mold cavity 13 so that the slurry fills the whole pouring mold cavity 13;
s3: when the movable parts 11 are deviated from the main body part 10 outwards, the movable parts are kept still for a period of time, when slurry in the pouring cavity 13 is in a semi-solidification state, the two movable parts 11 are pushed oppositely, the two movable parts 11 rotate towards the central axis direction of the pouring cavity 13, so that the movable parts 11 are deviated from the main body part 10 inwards, the deviation angle is beta (as shown in fig. 3 and 5), the top of the pouring cavity 13 is contracted, the slurry in the pouring cavity 13 is extruded, air bubbles in the slurry are extruded out quickly, the top ends of the movable parts 11 move along the supporting beam 2 by the same displacement amount in the rotating process, and the telescopic parts 12 are pulled apart along with the rotation of the movable parts 11, so that the top ends of the movable parts 11 are always abutted to the supporting beam 2. It should be noted that, when the casting cavity is built, if the movable part is offset inwards, after the casting of the slurry in the casting cavity 13 is completed, the movable part 11 does not need to be moved, and a contraction structure can also be formed on the top of the wall body.
By adopting the processing method, no matter the movable part deviates inwards or outwards in the process of building the pouring die cavity, the top of the wall body does not need to be trimmed after pouring is finished, so that the process of manually trimming the top of the wall body is omitted, and the construction speed is effectively improved. In addition, if the movable part deviates outwards in the process of building the pouring die cavity, the volume of the pouring die cavity 13 is greatly reduced due to the rotation of the movable part 11 on the pouring template 1, so that the pouring work of the wall body can be completed only by one-time pouring, and the construction speed and the construction quality are further improved. Preferably, the telescoping member 12 is a hydraulic ram, but could be a pneumatic ram or other powered telescoping device.
Further, as shown in fig. 2 to 4, when the movable portion 11 rotates to extrude the slurry, in order to facilitate the exhaust of the casting cavity 13, a first opening 14 is formed on a side wall of the main body portion 10 of the casting formwork 1, an exhaust pipe 3 is installed at the first opening 14, an opening at an upper end of the exhaust pipe 3 is higher than the support beam 2, a first valve M1 is further installed at the first opening 14, and the first opening 14 is communicated with the exhaust pipe 3 through the first valve M1. In the process of pouring the slurry, the first valve M1 is opened, the exhaust pipe 3 is communicated with the pouring die cavity 13, air escaping from the slurry in the pouring die cavity 13 can be exhausted through the exhaust pipe 3, and in the process of rotating the movable part 11 to extrude the slurry, the first valve M1 is closed. In addition, since the upper end opening of the exhaust pipe 3 is higher than the casting cavity 13, the slurry does not leak from the exhaust pipe 3. According to the communicating vessel principle, after the slurry in the casting cavity 13 passes through the first opening 14, the slurry height line in the casting cavity 13 is flush with the slurry height line in the exhaust pipe 3, so that, in a further improvement, the exhaust pipe 3 is made of a transparent material, and the upper end of the exhaust pipe 3 is provided with an indicating line 31 (as shown in fig. 2) for indicating that the slurry in the casting cavity 13 is full. When the slurry in the exhaust pipe 3 rises to the position of the indication line 31, the slurry can be stopped pouring into the pouring mold cavity 13.
Preferably, as shown in fig. 3, an electronic sensor 30 may be further disposed at the upper end of the exhaust pipe 3 or the movable portion 11, and when the slurry reaches the position of the electronic sensor 30, the electronic sensor 30 sends a detection signal for stopping the slurry pouring. In this embodiment, the electronic sensor 30 may be a photoelectric sensor, and when the control center detects that the feedback signal of the electronic sensor 30 changes, it indicates that the slurry in the exhaust pipe 3 has reached the position of the electronic sensor 30, and at this time, the control center may automatically turn off the casting pump, so as to stop pouring the slurry into the casting cavity 13.
Furthermore, a second opening portion 15 is formed in the side wall of the main body portion 10 of the pouring formwork 1, a second valve M2 and the feeding pipe 4 are arranged on the second opening portion 15, and the second opening portion 15 is communicated with the feeding pipe 4 through the second valve M2. When slurry is poured into the pouring die cavity 13, the second valve M2 is opened, the slurry enters the pouring die cavity 13 through the feeding pipe 4, and when the pouring die cavity 13 is filled, the second valve M2 is closed and feeding is stopped.
In order to realize automatic control, the first valve M1 and the second valve M2 in the above embodiments are both solenoid valves.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
